“…The range of these methods is vast, extending from auditory encoding techniques, such as textual descriptions conveyed through speech [91], [95]- [97], to sonification, the use of non-speech sounds [42], [91], [98]- [101]. Other methods involve advanced haptic feedback systems [87], [88], [102], and physicalization for tactile representations [69], [89], [103]- [107].…”

The increasing ubiquity of data in everyday life has elevated the importance of data literacy and accessible data representations, particularly for individuals with disabilities. While prior research predominantly focuses on the needs of the visually impaired, our survey aims to broaden this scope by investigating accessible data representations across a more inclusive spectrum of disabilities. After conducting a systematic review of 152 accessible data representation papers from ACM and IEEE databases, we found that roughly 78% of existing articles center on vision impairments. In this paper, we conduct a comprehensive review of the remaining 22% of papers focused on underrepresented disability communities. We developed categorical dimensions based on accessibility, visualization, and human-computer interaction to classify the papers. These dimensions include the community of focus, issues addressed, contribution type, study methods, participants, data type, visualization type, and data domain. Our work redefines accessible data representations by illustrating their application for disabilities beyond those related to vision. Building on our literature review, we identify and discuss opportunities for future research in accessible data representations.

“…Their tools, called Graph Builder and Sound Bar, combine haptic feedback using the PHANToM with nonspeech audio feedback. Another example of haptic graph representations using hardware solutions such as the PHANToM has been discussed by Doush et al [2013], who are working on a multimodal system for presenting Excel TM sheets, which are made accessible to people with visual impairments using haptic and aural feedback [Doush et al 2009;Doush et al 2010]. They use the Novint Falcon haptic device to provide haptic feedback.…”

The UN Convention on the Rights of Persons with Disabilities Article 24 states that "States Parties shall ensure inclusive education at all levels of education and life long learning." This article focuses on the inclusion of people with visual impairments in learning processes including complex table-based data. Gaining insight into and understanding of complex data is a highly demanding task for people with visual impairments. Especially in the case of table-based data, the classic approaches of braille-based output devices and printing concepts are limited. Haptic perception requires sequential information processing rather than the parallel processing used by the visual system, which hinders haptic perception to gather a fast overview of and deeper insight into the data. Nevertheless, neuroscientific research has identified great dependencies between haptic perception and the cognitive processing of visual sensing. Based on these findings, we developed a haptic 3D surface representation of classic diagrams and charts, such as bar graphs and pie charts. In a qualitative evaluation study, we identified certain advantages of our relief-type 3D chart approach. Finally, we present an education model for German schools that includes a 3D printing approach to help integrate students with visual impairments.

Images convey essential information in science, technology, engineering, and mathematics communication. Current guidelines on publishing recommend making images accessible to all readers. However, academic publishers do not always follow these guidelines and therefore fail to guarantee access by all readers to the visual content of academic articles. People with severe visual impairments cannot access the visual content of images unless a text alternative describing the images is provided. This study investigates the current use of texts commonly related to images in academic articles, such as captions and mentions, in order to assess their suitability as potential text alternatives to the images for readers who are blind or have severe low vision. A sample of 30 academic articles in the fields of biomedicine, computer science, and mathematics was analyzed and quantitative and qualitative data were collected about images and their related texts. We suggest a practical and sustainable solution that can foster the adoption of good accessibility practices by authors and publishers and facilitate their inclusion in regular publishing workflows.
